La multitemporalidad cumple una función importante en la novela “Condiciones Extremas” (1998, 2000 y 2005) del colombiano Juan B. Gutiérrez. Este texto es una hipernovela que presenta una organización narrativa temporal desfamiliarizadora anclada en las tendencias temáticas y estrategias textuales generales de las obras de ciencia ficción. La dispersión de la subjetividad de los personajes se observa en la narrativa y en la representación del texto como un hipermedia adaptable en donde la manipulación del elemento temporal es un aspecto esencial (...) en la interpretación de la narrativa digital. En la presentación y estructuración de su narrativa, “Condiciones Extremas” utiliza Literatrónica en su última versión. Éste es un motor de inteligencia artificial que preselecciona vínculos para que el lector-usuario siga en la construcción de la(s) historia(s) de la obra. Literatrónica trata de evitar la posible dispersión del sujeto-lector que se asocia con las múltiples alternativas de navegación de un hipertexto, proporcionándole a su lector-usuario una narrativa coherente, al estilo de las narrativas no-virtuales, presente desde el principio. De tal forma que cualquiera que sea la ruta de navegación por la que el lector-usuario opte, no se va a impedir una experiencia narrativa “completa” de la novela. (shrink)

This paper examines the challenge that psychoanalytic theory cannot be refuted. It does so by considering the theory in its orthodox Freudian form, and in the main branches into which it can be divided ? the theory of Instincts, of Development, of Psychic Structure, of Mental Economics or Defence, and of Symptom Formation. The essential character of the generalizations and concepts of these branches will just be indicated; and we shall ask of each branch whether it is possible to refute (...) it. A considerable amount of scientific enquiry has been done into the concepts and generalizations of psychoanalysis. Relevant examples of these enquiries will be noted; and the question asked whether these scientific studies have in fact done anything to refute or support the various branches of psychoanalytic theory. The general upshot will be that the challenge is both important and a mistake. (shrink)

This book applies philosophical hermeneutics to biblical studies. Whereas traditional studies of the Bible limit their analysis to the exploration of the texts' original historical sense, this book discusses how to move beyond these issues to a consideration of biblical texts' existential significance for the present. In response to the rejection of biblical significance in the late nineteenth century and the accompanying crisis of nihilism, B. H. McLean argues that the philosophical thought of Heidegger, Bultmann, Gadamer, Habermas, Ricoeur, Levinas, Deleuze (...) and Guattari provides an alternative to historically oriented approaches to biblical interpretation. He uses basic principles drawn from these philosophers' writings to create a framework for a new 'post-historical' mode of hermeneutic inquiry that transcends the subject-based epistemological structure of historical positivism.

Whereas previous discussions on ownership of biological material have been much informed by the natural rights tradition, insufficient attention has been paid to the strand in liberal political theory represented by Felix Cohen, Tony Honoré, and others, which treats property relations as socially constructed bundles of rights. In accordance with that tradition, we propose that the primary normative issue is what combination of rights a person should have to a particular item of biological material. Whether that bundle qualifies to be (...) called “property” or “ownership” is a secondary, terminological issue. We suggest five principles of bodily rights and show how they can be applied to the construction of ethically appropriate bundles of rights to biological material. (shrink)

The thesis that there can be vague objects is the thesis that there can be identity statements which are indeterminate in truth-value (i.e., neither true nor false) as a result of vagueness (as opposed, e.g., to reference-failure), "the singular terms of which do not have their references fixed by vague descriptive means". (if this is "not" what is meant by the thesis that there can be vague objects, it is not clear what "is" meant by it.) the possibility of vague (...) objects should not be taken, in itself, to imply the more radical thesis that the identity relation can be one of "degree". one can hold that the concept of degrees of identity is absurd (how can one thing be more or less identical to another?) "and" that indeterminacy in identity is possible; hence, any incoherence in the idea of degrees of identity does not thereby undermine the idea of indeterminate identity. (shrink)

Large-scale genetic databases are being developed in several countries around the world. However, these databases depend on public participation and acquiescence. In the past, information campaigns have been waged and little attention has been paid to dialogue. Nowadays, it is important to include the public in the development of scientific research and to encourage a free, open and useful dialogue among those involved. This paper is a review of community consultation strategies as part of four proposed large-scale genetic databases in (...) Iceland, Estonia, United Kingdom and Quebec. The Iceland Health Sector Database and Estonian Genome Project have followed a “communication approach” in order to address public concerns, whereas, UK Biobank and Quebec CARTaGENE have chosen a “partnership approach” to involve the public in decision-making processes.

Exploring the putative role of nature in human well-being has typically been operationalized and measured within a quantitative paradigm of research. However, such approaches are limited in the extent to which they can capture the full range of how natural experiences support well-being. The aim of the study was to explore personal experiences in nature and consider how they might be important to human health and well-being. Based on a descriptive phenomenological analysis of fifty descriptions of memorable moments in nature (...) from England, Indonesia, and Norway, our findings illustrate a common structure presented under three themes: 1. serenity that gives rise to a growing awareness of how the body is stimulated by the senses; 2. admiration and appreciation for the sensation of beauty; 3. an emerging sense of togetherness and deep emotional bonding. The findings are discussed using the concepts of ecological time and the ecological body, which foreground being in nature as constituted as an interdependent and dynamic human process. We conclude by understanding well-being in terms of human responsiveness to their surroundings and thus as rooted in the human condition. (shrink)

Philosophy of science education can play a vital role in the preparation and professional development of science teachers. In order to fulfill this role a philosophy of science education should be made practical for teachers. First, multiple and inherently incomplete philosophies on the teacher and teaching on what, how and why should be integrated. In this paper we describe our philosophy of science education which is composed of bounded rationalism as a guideline for understanding teachers’ practical reasoning, liberal education underlying (...) the why of teaching, scientific perspectivism as guideline for the what and educational social constructivism as guiding choices about the how of science education. Integration of multiple philosophies into a coherent philosophy of science education is necessary but not sufficient to make it practical for teachers. Philosophies are still formulated at a too abstract level to guide teachers’ practical reasoning. For this purpose, a heuristic model must be developed on an intermediate level of abstraction that will provide teachers with a bridge between these abstract ideas and their specific teaching situation. We have developed and validated such a heuristic model, the CLASS model in order to complement our ASSET approach. We illustrate how science teachers use the ASSET approach and the CLASS model to make choices about the what, the how and the why of science teaching. (shrink)

The eleventh-century Byzantine compiler Cedrenus includes a unique story in the midst of his otherwise traditional and hagiographic material on the emperor Constantine. Mentioning the outbreak of war between the Roman and Persian empires, he describes the cause of the breakdown of peace somewhat as follows. A certain Metrodorus, who was of Persian origin, went to visit the Brahmins in India to study philosophy and won the reputation of being a holy man through his asceticism. He also built water mills (...) and baths, unknown to the Indians till that time. Having acquired this reputation, he entered the temples and took away many precious stones and pearls. He also received gifts from the king of the Indians. On his return to Byzantium he gave them to the emperor Constantine as being gifts of his own. When Constantine expressed his astonishment, Metrodorus said he had sent other gifts by the land route but that they had been detained by the Persians. Constantine then wrote a strong protest to Sapor demanding the gifts but received no reply; thus the peace was broken. This remarkable conte, more appropriate to the Arabian Nights than to sober history, is generally supposed to be referred to in a passage in Ammianus. Towards the end of a long section commenting on the personality and achievements of Julian, Ammianus turns briefly to the question of the ultimate responsibility for the Persian War which ended so disastrously for Julian and the Roman Empire: et quoniam eum obtrectatoribus novos bellorum tumultus ad perniciem rei communis insimulant concitasse, sciant docente veritate perspicue, non Iulianum sed Constantinum ardores Parthicos succendisse, cum Metrodori mendaciis avidius acquiescit, ut dudum rettulimus plane.

Some believe that there is a God who is the source of all things; and some believe that there are necessarily existing abstract objects. But can one believe both these things? That is the question of this Element. First, Einar Duenger Bøhn clarifies the concepts involved, and the problem that arises from believing in both God and abstract objects. Second, he presents and discusses the possible kinds of solutions to that problem. Third, Bøhn discusses a new kind of solution to (...) the problem, according to which reality is most fundamentally made of information. (shrink)

Ten new graduate speech pathologists recounted their experiences in managing workplace ethical dilemmas in semi-structured interviews. Their stories were analysed for elements that described the nature and management of the ethical dilemmas. Ethical reasoning themes were generated to reflect the participants’ approaches to managing these dilemmas. Finally, a conceptual model, the Dynamic Model of Ethical Reasoning, was developed. This model incorporates the elements of awareness, independent problem solving, supported problem solving, and decision and outcome evaluation. Features of the model demonstrate (...) the complexity of ethical reasoning and the challenges that new graduates encounter when managing ethical dilemmas. The results have implications for preparing new graduates to manage ethical dilemmas in the workplace. (shrink)

We interpret the concept of determinism for a classical system as the requirement that the solution to the Cauchy problem for the equations of motion governing this system be unique. This requirement is generally believed to hold for all autonomous classical systems. Our analysis of classical electrodynamics in a world with one temporal and one spatial dimension provides counterexamples of this belief. Given the initial conditions of a particular type, the Cauchy problem may have an infinite set of solutions. Therefore, (...) random behavior of closed classical systems is indeed possible. With this finding, we give a qualitative explanation of how classical strings can split. We propose a modified path integral formulation of classical mechanics to include indeterministic systems.

Professor Kemp Smith in providing a new edition of Hume’s Dialogues Concerning Natural Religion , embodying all the author’s additions and corrections, has given expression to the perennial interest and fascination which this work has possessed for many minds during the odd one hundred and fifty years since it was first published by Hume’s nephew. The editor himself has performed a great service by contributing an Introduction and a clear and concise summary of the Dialogues , in both of which (...) he expounds his own view as to how Hume’s discussion is to be interpreted. Hume employs three characters—Demea, Philo, and Cleanthes; and. (shrink)

As philosophers in the continental tradition have taken an interest in the return of religion, anthropologists and sociologists have rejected the once-dominant secularization thesis. Bradley B. Onishi connects these lines of thought to reveal how philosophy's religious investigations have enabled critical reflections on the category of the secular.

Chaos theory is a rapidly growing field. As a technical term, chaos refers to deterministic but unpredictable processes being sensitively dependent upon initial conditions. Neurobiological models and experimental results are very complicated and some research groups have tried to pursue the neuronal chaos. Babloyantz's group has studied the fractal dimension (d) of electroencephalograms (EEG) in various physiological and pathological states. From deep sleep (d=4) to full awakening (d>8), a hierarchy of strange attractors paralles the hierarchy of states of consciousness. In (...) epilepsy (petit mal), despite the turbulent aspect of a seizure, the attractor dimension was near to 2. In Creutzfeld-Jacob disease, the regular EEG activity corresponded to an attractor dimension less than the one measured in deep sleep. Is it healthy to be chaotic? An active desynchronisation could be favourable to a physiological system. Rapp's group reported variations of fractal dimension according to particular tasks. During a mental arithmetic task, this dimension increased. In another task, a P300 fractal index decreased when a target was identified. It is clear that the EEG is not representing noise. Its underlying dynamics depends on only a few degrees of freedom despite yet it is difficult to compute accurately the relevant parameters.What is the cognitive role of such a chaotic dynamics? Freeman has studied the olfactory bulb in rabbits and rats for 15 years. Multi-electrode recordings of a few mm2 showed a chaotic hierarchy from deep anaesthesia to alert state. When an animal identified a previously learned odour, the fractal dimension of the dynamics dropped off (near limit cycles). The chaotic activity corresponding to an alert-and-waiting state seems to be a field of all possibilities and a focused activity corresponds to a reduction of the attractor in state space. For a couple of years, Freeman has developed a model of the olfactory bulb-cortex system. The behaviour of the simple model without learning was quite similar to the real behaviour and a model with learning is developed. (shrink)

Recently Steven E. Boër gave another turn to the discussion of the free will defence by claiming that the free will defence is irrelevant to the justification of moral evil. Conceding that free will may be of real value, Boër claims that free will could have been allowed creatures without that leading to any moral evil at all. What I shall hereafter refer to as the ‘Boër reform’ is the suggestion that God could have allowed creatures to exercise free choices (...) but have intervened with ‘coincidence miracles’ to prevent all the intended evil from actually occurring. What is important to the free will defence, according to Boër, is the ability to choose freely and not the ability to succeed in effecting what we have intended to accomplish. It is no intrusion on the freedom of our wills for God to prevent us from accomplishing what we tried to do with our free wills as long as we were free to try. (shrink)

This paper seeks to examine two conflicting strands in the United States Supreme Court's treatment of “freedom of association,” by exploring some aspects of the historical development of the doctrine. It suggests that there are two conceptions of “freedom of association,” an older, traditional one, that eschews forcing odious contact on members of associations, and a newer one which privileges antidiscrimination doctrines over “freedom from association.” These two conceptions still exist on the Court, resulting in irreconcilable decisions such as those (...) permitting the Boy Scouts to exclude gay scoutmasters, but forcing the Jaycees to accept women. The preference of one conception over the other is also evident in the work of different scholars, whose doctrinal approaches are similarly irreconcilable. The Supreme Court has explained the discontinuities in the doctrine by seeking to characterize it in terms of the First Amendment's “freedom of speech” clause, but the paper argues that it makes more sense, in the context of these two cases, to regard them as related to the First Amendment's “freedom of religion” clauses.

I submit as a good rule of thumb that if a discussion of any major philosophical position or proposition ends with the conclusion that that position or proposition is ‘absurd’ or ‘meaningless’ then a mistake has been made in the discussion. The mistake often turns out to be the accuser's failure to appreciate precisely what the position being attacked really is.

Resurrection has been used as the conceptual basis for attempted solutions to two problems that occur in the context of western theism, the problem of cognitive meaning and the problem of theodicy. Because John Hick has proposed resurrection as a solution to both problems so extensively, and because Antony Flew and Terence Penelhum have examined those solutions so strenuously, I will use their writings to lay out the problem. My aim is to improve upon Hick by overcoming a weakness in (...) his defence of resurrection. My narrower focus will be on resurrection and the ‘replica objection’, rather than the wider use of resurrection to solve problems of evil or the meaningfulness of theistic discourse, but some brief remarks on the wider problems will be necessary to set the stage.
